Review: Best value for money - Amazing value for the money. You’ll need to spend much more to get better sound. Review: Been using for 2 weeks now, plugged into a JBL Partybox 120 from Technics 1200 and have no complaints! Great little preamp that makes the vinyl sound pop with full spectrum sound, mids and accents well distinguished. Very simple to use, once you dial in the db level selector it does the rest and you control the volume on your amp. Low key but good price for the value IMO. Far better than a basic solid state preamp i was using for the past month that boosted the signal but was not as dynamic soundwise. And 1000% better than a more expensive tube preamp that was returned within 2 days b/c it compromised the high and low end. That one looked super cool but had to go. ## Features - High Performance: The BOX X5 phono preamp is compatible with both MM and MC cartridges, featuring 4 gain settings and an excellent precise RIAA equalization to provide a clean, direct pass-through of a signal when paired with your turntable - Audiophile-Grade Components: This preamp utilizes a variety of materials such as 2% Precision Polyester Film Capacitors, Green Sleeve Copper Lead Audio Capacitors, 0.1% High-Precision Film Resistors, OPA1612 Op-Amp, Gold-Plated RCA Jacks, and more.
